The main site of Japan's experiments into biological warfare was the prisoner of war camp known as Unit 731 located in Pingfan, Manchuria, where Chinese inmates were subjected to gruesome experiments aimed at testing the limits of the human body and the effectiveness of biological and chemical agents. [71] Harris also said plague-infected animals were released near the end of the war, and caused plague outbreaks that killed at least 30,000 people in the Harbin area from 1946 to 1948.

One element of the unit, called "Maruta," took this research a little further than the usual bounds of medical ethics by observing injuries and the course of disease on living patients. The totality of Unit 731s research was in support of their larger mission, which by 1939 was to develop horrific weapons of mass destruction for use against the Chinese population, and presumably American and Soviet forces, if the time ever came. The fleas were then packed in dust and sealed inside clay bomb casings. He gave up the idea, left and locked the door, then later went on to his experimental work. Operations and experiments continued until the end of the war. However, he rejected victims' compensation claims on the grounds that they had already been settled by international peace treaties. To determine the best course of treatment for varying degrees of shrapnel wounds sustained on the field by Japanese Soldiers, Chinese prisoners were exposed to direct bomb blasts. The ministry alleged that no academic research supported the claim. [112] Critics argue that racism led to the double standard in the American postwar responses to the experiments conducted on different nationalities.
